Development and function of consequence classes in operant behavior.

The term class has been discussed extensively in the behavioral literature for groups of stimuli or responses that share a common function. In contrast, the concept of consequence class, including its definition, its formation, and other relevant characteristics, has not been the topic of much attention in the literature. Issues pertaining to consequence classes are discussed to provide a more thorough analysis of the units of operant and discriminated operant functional relations. The concept of class for consequences provides a means to integrate data and theory from the behavior-analytic literature.
